Ramcharger fusable link question

I have no clue where the actual fault is.
You have a large gauge wire there with 4 fusible link branching from it. One link burned away to no longer usable. rather than whittle into the factory fancy molded branch block you could replace the fusible link and add a wire all the way to wherever that original feed wire comes from, or cut the entire branch block out and put all the connections on a threaded contact post with ring terminals. That is what I would do. Ford loaded there fusible link contacts on their starter solenoid. GM and others used a contact/terminal post. Feck ma mopars unserviceable way to do it.
